OnlyWin Casino flexes its muscles with a First Deposit Bonus offer that demands attention. This review cuts through the hype to examine their 100% match up to €400 plus 100 free spins on Flexing Dragons. We’ll dissect every aspect of this offer, from its dragon-sized potential to its hidden pitfalls, helping you decide if OnlyWin’s bonus truly lives up to the casino’s name.

Bonus Structure
The OnlyWin Casino Welcome Bonus is a two-part offer consisting of a deposit match and free spins:
- Deposit Match: 100% match up to €400
- Free Spins: 100 Free Spins on Flexing Dragons
Let’s break down each component:
Deposit Match
The 100% match means that OnlyWin Casino will double your initial deposit, up to a maximum of €400. For example:
- If you deposit €50, you’ll receive an additional €50 in bonus funds, giving you €100 to play with.
- If you deposit €300, you’ll receive an additional €300, totaling €600 in your account.
- If you deposit €500, you’ll receive the maximum bonus of €400, giving you €900 to play with.
Free Spins
The 100 Free Spins are distributed over 5 days:
- 20 Free Spins per day for 5 consecutive days
- Free Spins must be activated within 5 days of receiving them
- Once activated, Free Spins are valid for 5 days
The Free Spins are exclusively for use on Flexing Dragons, an exciting slot game developed by OneTouch. Here are the key details about this game:
- Game Type: 6-reel, 7-row video slot with 117,649 betways
- RTP (Return to Player): 96.05%
- Volatility: High
- Minimum Bet: €0.40

Flexing Dragons is known for its Asian theme and potential for significant wins, especially during the extra spins feature. The high volatility means that while wins may be less frequent, they can be substantial when they occur.

Wagering Requirements
The bonus comes with a 40x wagering requirement on both the bonus amount and any winnings from free spins. This means you’ll need to wager the bonus funds and free spin winnings 40 times before you can withdraw any associated winnings.

Maximum Bet Restriction
While playing with bonus funds, the maximum allowed bet is €5 per spin. This restriction is in place to prevent bonus abuse and ensure fair play.
Game Restrictions

Bonus Cash-Out Limits

While specific deposit method restrictions weren’t mentioned, it’s generally advisable to use bank transfers, credit/debit cards, or the listed cryptocurrencies to ensure bonus eligibility.
Value Assessment
The OnlyWin Casino Welcome Bonus offers good value for players. The 100% match up to €400 is generous and above many industry standards. The addition of 100 Free Spins adds extra value, allowing players to try out the exciting Flexing Dragons slot without risking their own funds.
The 40x wagering requirement is in line with industry standards, which typically range from 30x to 50x. This requirement means that clearing the bonus will be challenging but not impossible within the 5-day time limit.
Strategic Approach
To maximize the value of this bonus, consider the following strategies:
- Deposit €400 to get the maximum bonus along with the 100 Free Spins.
- Focus on playing slots, as they typically contribute 100% towards wagering requirements.
- Use your Free Spins on Flexing Dragons as soon as they’re available each day.
- Keep your bets at or below the €5 maximum to avoid violating bonus terms.
- Try to clear the wagering requirements as quickly as possible within the 5-day window.
Conclusion
The OnlyWin Casino Welcome Bonus review reveals a potentially lucrative start for new players, with a generous match bonus and a good number of Free Spins. The wagering requirements are fair, but the short time frame for meeting them presents a challenge.
Players should carefully consider their gambling budget and play style before opting in for this bonus. While it offers good value, it’s best suited for regular players who can dedicate sufficient time and funds to meet the wagering requirements within the stipulated period. Remember to always gamble responsibly and read the full terms and conditions before claiming any casino promotion.
